Allow non-socket connections to redis

[simontabor]

It'd be nice to be able to specify a host and a port instead of being forced to use redis.sock.

Happy to give implementing this a go if you'd like

I can see the use case (not enough memory/resources on a single machine), but this is not recommended - using a unix socket is much faster. This is not a priority for me, but I will take a look at a pull if you want to submit one.

I have changes over at https://github.com/anthroprose/skyline that will fix this issue and are a much smaller changeset than the last Pull Req. Are these still wanted/welcome?
